Viterbi Decoding for Convolutional Code over Class A Noise Channel

Power line channel often suffers from impulsive interferences generated by electrical appliances. Therefore, power line communication (PLC) suffers the degradation due to such the impulsive interferences. Middleton’s Class A noise model is frequently utilized for the modeling of such the impulsive noise environment. In this paper, we deal with the Viterbi decoding for convolutional code over additive white Class A noise (AWAN) channel. We propose a Viterbi decoder for convolutional code optimized in AWAN channel. In addition, we show the performance of the proposed Viterbi decoder for convolutional code in Class A noise environment by computer simulation.
